POCKET LAMP.

Application filed June 7, 1927, Serial No. 197,184, and in GermanyJanuary 81, 1987.

Mechanical pocket-lamps are known in which, by compressing of asegment-lever a gear wheel mechanism is operated so that by the same thecerium-stones are made to rotate in sliding upon an emery-disk so thatThe inconveniences are avoided, according to the invention whlch relatesto a pocketlamp ofsimple and cheap construction.

According to the invention a toothed-wheelmechanism on whichcerium-stones, a refleeting plate and a ray-regulator are mounted, israpidly rotated by means of a spring-controlled rack, the bushels ofsparks which are produced being rejected by the ray-regulator upon theparaboloidal reflecting wall of a casing so that the light rays areprojected through a lens.

An embodiment of the invention is shown, by way of example, in theaccompanying drawing, in Fig. 1 in section and in Fig. 2 in top planview.

. In slots of the end walls of a casing a a rack 12 is guided whichengages with a pinion f on a vertical shaft 0 said shaft being.shiftably mounted in said casing. Byja pressure exerted upon the outerend of rack the vertical shaft 0 shifted in being r0- tated at the sametime so that a spur-wheel d, rigid with the pinion f comes into gearwith a pinion g which is thus rapidly rotated together with the verticalshaft h on one end to the front wall of the casing and at the other endto the inner end of rack 12- paraboloidal wall Z at the top end ofwhich,

y means of a mounting m, a lens at is screwed.

B0 The vertical shaft It carries onits portion,

'ing end of rack b the shaft h carrying the which it is keyed. A spring11, fixed at the bent downward between which vibrating lever g aresuspended which carry each a cerium-stone r at the outer end. A nut sscrewed on the threaded top end of shaft it serves to secure theregulator 0 with the vibrating-levers g in their position.

The operation is as follows By a pressure exerted upon theprojectray-regulator and the vibrating levers with the cerium-stones israpidly rotated through the intermediary of the gear wheels f, d, 9 sothat bushels of sparks are produced by the cerium-stones sliding on theemery-disk it. These sparks strike onto the ray-regulator whichprojectsthe same onto the reflecting surface so that the light produced isprojected through the lens. The ray-regulator serves at the same time asfly-wheel so that the spark-production, continues even during thereturn-movement of the rack.

I claim 1. A pocket-lamp comprising in combi: nation with a casing, anemery disk mounted on said casing, a vertical shaft journalled insaidcasing, means for rapidly rotating said vertical shaft, :1. paraboloidalcasing having a reflecting inner surface, a lens in the top end of saidcasing, a ray-regulator fixed on said vertical axle, and elastic leverssuspended underneath said ray-regulator and having at the end acerium-stone resting upon said emery-disk sothat the sparks produced bythe rapid movement of said ceriumstones are thrown by said ray-regulatoronto said reflecting surface and the light-rays projected through saidlens.

2. A pocket-lamp comprising in combi-' nation with a casing, an emerydisk mounted on said casing, a vertical shaft journalled in said casing,means for rapidly rotating said vertical shaft, a paraboloidal casinghaving a reflecting inner surface, a lens in the top end of said casing,a ray-regulator 1 fixed on said vertical axle and consisting of thesparks produced by the rapid movement a horizontal flat-bar withsector-sha ed ends of said cerium-stones are thrown by said and servingat the same time as y-wheel, ray-regulator onto said reflecting surface10 downwardly bent flaps at the middle of said and the light-raysprojected through said 5 bar, elastic arms suspended between said lens.flaps, a cerium-stone at the end of each arm In testimony whereof Iaflix my signature. and resting upon said emery disk, so that CARLARNOLD.
